Jeremiah 51:34

"Nebuchadnezzar the king of Babylon hath devoured me, he hath crushed me, he hath made me an empty vessel, he hath like a monster swallowed me up, he has filled his maw with my delicacies; he hath cast me out. The violence done to me and to my flesh be upon Babylon, shall the inhabitant of Zion say; and, My blood be upon the inhabitants of Chaldea, shall Jerusalem say. Therefore thus saith Jehovah: Behold, I will plead thy cause, and take vengeance for thee; and I will dry up her sea, and make her fountain dry. And Babylon shall become heaps, a dwelling place for jackals, an astonishment, and a hissing, without inhabitant. They shall roar together like young lions; thy shall growl as lions' whelps. When they are heated I will make their feast, and I will make them drunken, that they may rejoice, and sleep a perpetual sleep, and not wake, saith Jehovah. I will bring them down like lambs to the slaughter, like rams with he-goats."

Harrison's summary of this paragraph has this:

"Nebuchadnezzar has devoured Jerusalem with the greedy gulp of a monster (the New English Bible has "dragon"), and for this excess his land shall be punished. The idiom of recompense (Jeremiah 51:35) is that of Genesis 16:5)."[16]

"I will dry up her sea, and make her fountain dry ..." (Jeremiah 51:36). This writer cannot believe that Almighty God would dignify the mythological tale of a vast underground ocean by here promising to dry it up. Could God dry up something that never existed? Therefore, we reject the notion that, "This is a reference to the mythological wellsprings of life."[17] The Euphrates and its system of canals were the wellsprings of life for Babylon, not some mythological underground sea. See under Jeremiah 51:13, above. Smith supposed that there might also be a reference here to, "The great lake dug by Nitocris to receive the waters of the Euphrates."[18]

"Like a monster ..." (Jeremiah 51:34). See my comment on Isaiah 27:1 regarding the monster mentioned there.
